Review and synthesis of the role of structural arches in the Brazilian Amazon lowlands
(East Carolina University, 2017-01-11)In tropical South America, the interplay of tectonics, climate, and base-level influences terrestrial sedimentary processes of modern rivers and their antecedents, leading to transport of large volumes of sediment through ... -
NUTRIENT AND BACTERIA DYNAMICS OF PACKAGE TREATMENT PLANTS IN COASTAL CARTERET COUNTY, NORTH CAROLINA
(East Carolina University, 2016-08-18)Nutrient and bacteria enrichment problems are well documented in the waterways along North Carolina's coast. Surface and subsurface wastewater inputs have been documented as a source of these pollutants in a variety of ... -
Back-Barrier Sediment and Hydrodynamic Processes: Insights from Rodanthe, NC
(East Carolina University, 2016-07-20)Barrier islands are found around the world, and their geomorphic evolution is related to ocean and estuarine processes. Processes including sediment mobilization and shoreline evolution on both the ocean and estuarine side ... -
The Relationship Between the Taghanic Unconformity and Marcellus Shale Production in Doddridge and Ritchie Counties, West Virginia
(East Carolina University, 2016-07-27)The Marcellus Shale, a geologic unit that extends from New York to West Virginia within the Appalachian region, is the source of trillions of cubic feet of natural gas due to organic-rich properties. The formation of the ... -
Petroleum Geology of the Utica/Point Pleasant Play in Washington County, Ohio
(East Carolina University, 2016-07-20)The early Late Ordovician interval, known as the Utica-Point Pleasant play, in southeastern Ohio is poorly constrained due to limited data sets. A previous study by the Appalachian Basin Oil and Natural Gas Research ... -
DISTRIBUTION AND TAXONOMY OF MODERN BENTHIC FORAMINIFERA OF THE WESTERN SUNDA SHELF (SOUTH CHINA SEA) OFF PENINSULAR MALAYSIA
(East Carolina University, 2016-07-13)This study investigates, for the first time, the distribution and taxonomy of modern benthic foraminifera from the western Sunda Shelf, southern South China Sea. The uppermost centimeter of 54 surface sediment samples ... -
Holocene Sedimentary Record from the Sunda Shelf off Peninsular Malaysia: Insights from Elemental, Isotopic and Bulk Sediment Magnetic Susceptibility Analyses
(East Carolina University, 2016-04-19)Post-Last Glacial Maximum (since ca. 20,000 cal yr BP) sediments of the Sunda Shelf (southern South China Sea) are generally thin, with the exception of incised valleys where thicker accumulations tend to occur. These ... -
Geophysical characterization of onsite wastewater treatment system effects on groundwater quality, eastern North Carolina
(East Carolina University, 1/13/16)Onsite wastewater treatment systems (OWS) are a potential non-point source of pollution that can result in water quality degradation in groundwater and surface water. Locating OWS wastewater plumes in the subsurface often ... -
THE MARCELLUS SHALE: EROSIONAL BOUNDARY AND PRODUCTION ANALYSIS, SOUTHERN WEST VIRGINIA, U.S.A.
(East Carolina University, 1/13/16)The Middle Devonian Marcellus Shale is a natural gas producing formation that was deposited in the Appalachian foreland basin in what is now eastern North America. An unconformity truncates the Marcellus in southern West ... -
Quaternary Evolution of North Core Sound Sound, North Carolina
(East Carolina University, 1/13/16)Northern Core Sound is a shallow lagoonal estuary located behind the Outer Banks barrier islands of eastern North Carolina. Thirty-two vibracores and 155 km of chirp and boomer seismic data have been used to define the ... -
Holocene Evolution of the Ocracoke Inlet Flood-tide Delta Region, Outer Banks, North Carolina
(East Carolina University, 1/13/16)Numerous studies have been conducted along the Outer Banks (OBX) barrier islands of North Carolina to address Holocene climatic change using a combination of lithological, micropaleontological, stratigraphical, and ... -
The Contentnea Creek Granite : Constraints On Late Paleozoic Magmatism And Deformation, Eastern Piedmont Fault System, North Carolina
(East Carolina University, 2015)The Alleghanian orogeny is manifested in eastern North Carolina by dextral transpressional faulting on the Eastern Piedmont Fault system and spatially associated granitic magmatism. The Contentnea Creek granite in Wilson ... -
Examining Coastal Marsh Sedimentation In Northeastern North Carolina
(East Carolina University, 2015)Coastal marshes are critical environments that are ephemeral on geologic timescales. Understanding the dynamics that naturally maintain these systems is becoming increasingly important in the face of accelerated sea-level ... -
Geometry and Construction History of the Copper Ridge Laccolith, Mount Ellen, Henry Mountains, Utah
(East Carolina University, 2015)The Copper Ridge laccolith is an asymmetric tongue-shaped intrusion located on the southeastern margin of Mount Ellen in the Henry Mountains, Utah. The late-Oligocene to early-Miocene igneous rocks have no syn- or ... -
Extension of the Late Holocene Sea-Level Record In North Carolina, USA
(East Carolina University, 2015)Future sea-level rise will dramatically affect coastal landscapes and populations. The coast of North Carolina (USA) is particularly vulnerable to sea-level rise because its low-lying coastal plain is expansive, has a low ... -
Modern Sedimentation And Estuarine Shoreline Change Around Roanoke Island, North Carolina
(East Carolina University, 2015)Croatan and Roanoke sounds in North Carolina (NC) are regions constantly undergoing geomorphic changes associated with sea-level rise, storm events, and anthropogenic modification. These estuaries are part of the larger ... -
Timing, internal flow characteristics, and emplacement mechanisms of the intrusive sheet network on the southern margin of Mount Hillers, Henry Mountains, southern Utah
(East Carolina University, 2015)The exceptional 3-d exposures of the mid-Tertiary intrusive sheet network on the southern margin of Mount Hillers, Henry Mountains, southern Utah, have undergone no syn- or post-emplacement deformation. The sills and ... -
